Application filea-nove teras, 1926. Seria1 l io.f150,t 71.g i J' The device of my invention relates to ventilators and refers particularly toventilating deflectors for w ndow use.

. One of'the objects of-my 1nvention isa ventilator in whichthe deflector element is readily attached to, and removed from the supporting side pieces. v Another object of my invention is a ventilator free from noise and rattle incidentto air impact; j

Another object of my inventionis aventilator made of inexpensive'material,

-Another object of my invention 1s alknockdown ventilator which canbe easily assem- In the accompanying drawings illustrating modified forms of the device of my in vention, similar parts are designated. by similar numerals. I

Figure 1 is a front view of one form of my device positioned within a window frame.

Figure 2 is a cross-section through the line 22 of Figure'l. l

Figure 3 is a cross-section through the line 3-3 of Figure 2.

Figure 4 is a perspective view of a hold,

ing member.

Figure 5 is a perspective view' of a deflector. v

Figure 6 is a fragmentary vertical cross section of a modified form of deflector.

The particular form of the device of my invention shown in the accompanying drawings comprises a corrugated cardboard deflector, having the central member 10 and the two angularly positioned truncated triangular end pieces 11, 1-1, the end pieces being formed by scoring the cardboard and",

bending upon the scoreline s. Each deflector end 11 has a plurality of recesses, or

slots, 12, 12 entering from its outer edge. The upper edge of the deflector is covered a by a protecting paper or textile member 13.

A U-shaped resilient metallic holding member 14, has one of its edges 15 bent inwardly and has a plurality of holes 16, 16, positioned in the two sides of'the holding member in alignment with each other and also positioned in alignment with the slots 12, 12 ofa deflector end 11, when the end 11 is positioned within the holding member.

A thumb screw 17 is capable of placement through aligned holes 16, 16 and a slot'12.

The operation of my device is as follows:

holding members 14, 14 are placed upon rigidly Y in proofed. I do not limit myself to theparticular size, shape, number, arrangement orfmate-- of holes. 16 and screwed into the window frame 18, thus fixedly attaching the holdl ing members to thetrame. i i I The two deflector ends 1 1,, 11 are then H w passed inwardly of the twojholders, the

screws 16, 16entering theslots- 12, 12.; The

the lower portions of the inner face s 5 posite sides of a window frame '18, with the opening inwardly toward the room, and a "thumb-screw 16 passed through each pair 6.

resiliency ofthe. holders 14, 14 will cause their edges 15, 15 togrip and hold the.deflector ends, or this gripping eflect'can be increased, itdesired, by. screwing the thumb screws slightly inwardly.

Theholdingmembers may be devoid 0t f I I the turned edges if desired, contact being maintained between theholding members and the deflector ends by pressure; caused by the thumb turned inwardly.

Inthis manner, the defl ctor will he held place, but-can be readily removed if desired.

In the modification: shown in Figure 6, a

s w, rbOts be v stiffening rod 19 is placed along the upper:

edge of the deflector central portion lO'and 7 below the covering, or binding, 13. s

It willbe noted that as the holding mem- 'bers' are fixedly attached to the window frame and as the deflector is non-metallic,

' there .can be no rattling effect. I 1

Further, it will be noted that as the deflector is of a yielding material, the edge 15 of the holding member willreadily set'itself into the deflectorto maintain it in position. I

By cardboard, I mean both ordinary cardboard and corrugated cardboard and. other similar materials maybe employed and the device maybe paintedand water rial of parts'as shown and described, as

these are given simply as a means or clearly" describing-my invention;

WVhat I claim is 1. In a window; ventilator, in combination, a stiff deflector of yieldable material,

having angularly I positioned end members,
